你有一个苹果，我有一个苹果

倘若你有一个苹果，我也有一个苹果，我们彼此交换一下，我们依然是各有一个苹果；倘若你有一个想法，我也有一个想法，我们彼此交流，那么，我们每个人将各有两个想法了。51Testing软件测试网0J)bD'y(~`N

If you have an apple and I also have an apple, and we exchange

apples, we both still only have one apple. But if you have an

idea and I also have an idea, and we exchange ideas, we each now

have two ideas.
